Cc: Marcel Holtmann Cc: Sathish Narsimman Fixes: 0eee35bdfa3b ("Bluetooth: Update resolving list when updating whitelist") Signed-off-by: Greg Kroah-Hartman --- net/bluetooth/hci_request.c | 41 ++----------------------------------- 1 file changed, 2 insertions(+), 39 deletions(-) This has been bugging me for since 5.9-rc1, when all bluetooth devices stopped working on my desktop system. I finally got the time to do bisection today, and it came down to this patch. Reverting it on top of 5.9-rc7 restored bluetooth devices and now my input devices properly work. As it's almost 5.9-final, any chance this can be merged now to fix the issue? diff --git a/net/bluetooth/hci_request.c b/net/bluetooth/hci_request.c index e0269192f2e5..75b0a4776f10 100644 --- a/net/bluetooth/hci_request.c +++ b/net/bluetooth/hci_request.c @@ -697,21 +697,6 @@ static void del_from_white_list(struct hci_request *req, bdaddr_t *bdaddr, bt_dev_dbg(req->hdev, "Remove %pMR (0x%x) from whitelist", &cp.bdaddr, cp.bdaddr_type); hci_req_add(req, HCI_OP_LE_DEL_FROM_WHITE_LIST, sizeof(cp), &cp); - - if (use_ll_privacy(req->hdev)) { - struct smp_irk *irk; - - irk = hci_find_irk_by_addr(req->hdev, bdaddr, bdaddr_type); - if (irk) { - struct hci_cp_le_del_from_resolv_list cp; - - cp.bdaddr_type = bdaddr_type; - bacpy(&cp.bdaddr, bdaddr); - - hci_req_add(req, HCI_OP_LE_DEL_FROM_RESOLV_LIST, - sizeof(cp), &cp); - } - } } /* Adds connection to white list if needed.
